Dear PARI developers,
I found a way to do a formal ellinit which is sometimes useful:
? a6;a4;a3;a2;a1;E=ellinit([a1,a2,a3,a4,a6],1);
? ##
*** last result computed in 0 ms.
This is useful because the more straightforward
a1;a2;a3;a4;a6;ellinit([a1,a2,a3,a4,a6],1);
does not really work (much much slower).
Cheers,
Bill.
